Pain acceptance contributes significantly to the effectiveness of pain treatment outcomes. Nevertheless, little research has been conducted to examine whether a decrease in acceptance contributes to a deterioration in post treatment functioning. The aim of this study was to assess the role of pain acceptance in relation to process and outcome variables in the six-months following the conclusion of a pain program. ⋯ Deterioration in acceptance of pain was significantly associated with deterioration in depression and disability, even when catastrophizing cognitions and kinesiophobia were accounted for. Decrease in acceptance was the strongest predictor of reliable deterioration in depression and disability. Results indicated the CPAQ-8 has utility as a measure for monitoring patient functioning post-treatment.
